Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Inspect and Replace Suspension Components

Tools Required: Socket set, torque wrench, floor jack, jack stands, impact wrench, pry bar.
Lift the vehicle using a floor jack and secure it on jack stands.
Check control arm bushings for wear. If damaged, remove the control arm by:
- Removing the bolts securing it to the subframe and strut.
- Disconnecting the sway bar link if necessary.
- Installing new bushings or control arms as needed.
- Torque the bolts to the manufacturer’s specifications (usually around 40-55 ft-lbs, but verify with service manual).

3. Inspect and Replace Steering Components

Check tie rods for wear; if damaged:
- Remove the nut securing the tie rod end to the steering knuckle.
- Use a tie rod puller to detach the tie rod.
- Install a new tie rod end and torque to specifications (typically around 30-45 ft-lbs).

4. Inspect and Replace CV Joints/Axles

Inspect the CV joints for torn boots or grease leakage. If damaged:
- Remove the wheel and brake assembly for access.
- Disconnect the axle from the wheel hub and the transmission.
- Install a new CV axle and reassemble all components, torquing to the recommended values.
